A lot of orthodontics is fixing things so someone can chew correctly, reducing pain etc. I'll assume that you didn't mean those folks.... Maybe you meant cosmetic dentistry, but even there, should we forever brand someone who didn't take care of their teeth earlier in life? What about folks who were given tetracycline when they were kids (which permanently stains their teeth)? Maybe there's a good example in dentistry, but let's see one. As to your "positional" argument, how are you separating out the "bad" positional change from "her teeth kept us from seeing his superior skills"? Or, is the latter also bad?
